Energy efficiency With regard to European Union directives, one of the main strands is to improve the energy efficiency of production processes. The main objective is to reduce greenhouse gas emissions, reduce overall energy consumption, make efficient use of available resources and recycle waste products, use waste heat and other waste resources. For this purpose, it is necessary to analyze the current energy consumption, its distribution over the time, as well as an analysis of the energy quality will be necessary. After analysis, measures can be prescribed to improve energy quality, reduce energy consumption, and prescribe and implement measures for self-production of energy from renewable energy sources, partially or wholly offsetting the energy consumption of the grid. Energy savings and production emissions will be promoted by the state through the issuance of white certificates that can be traded on stock exchanges.
